Abstract:	Values of the coefficients C₃ and C₅ which describe the asymptotic potential energy between an atom or molecule and a surface, and the constants C_s1 and C_s2 which characterize the surface mediation of the long-range atom(molecule)-atom(molecule) interaction, are calculated for rare gas and alkali or simple molecules, such as NO, H₂, and H₂O, adsorbed on noble and transition metals. These calculated results are obtained using analytic representations of the atomic polarizability and a numerical treatment of the substrate dielectric response obtained from measured optical constants.
